Confused And Need Help!!!

Hey guys as many of you know I pretended to own a McLaren and decided to confess that I didn't. I wanted to get a new and honest start. I was a very confused individual. One day I wanted to be an engineer, the next day a lawyer, the day an architect, and the next day a computer programmer. Almost all of the professions I thought of going into I only chose because I heard of people making big time bucks in those fields. I wasn't sure about anything but my love for cars. I decided I to go to school for business so that when I get out I can get a job as a car salesman for an exclusive dealership. I would love to sell FERRARI's and LAMBORGHINI's, but I know you could only get those positions with time and experience. I finally realized that everyone wants to own an exotic car, but the fact is that not everyone can, because than they wouldn't be exotic. I would rather be involved in selling them than not being involved with them at all. Do you guys think that the path that I have finally decided to take sounds like a good one? Do you think that having a degree in Business would make more marketable among the exclusive dealerships? If not, what route would be better for me to take so that one day I will be able to at least sell the exquisite automobiles. Any insight to this would be extremely appreciated.

Oh yeah one more thing. I was wondering what field of business would be better for me to study so I could accomplish my goal. Accounting, Management, Finance, Marketing, Business Economics, or Business Administration. I was thinking that Management would help me to accomplish my goal. But I could be wrong.
